| CVE-2022-41556 | 2 Fedoraproject, Lighttpd | 2 Fedora, Lighttpd | 2022-12-02 | N/A | 7.5 HIGH |
| A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected. This is fixed in 1.4.67. | |||||
| CVE-2022-37797 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2022-12-02 | N/A | 7.5 HIGH |
| In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could be used by an external attacker to cause denial of service condition. | |||||
| CVE-2022-30780 | 1 Lighttpd | 1 Lighttpd | 2022-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| Lighttpd 1.4.56 through 1.4.58 allows a remote attacker to cause a denial of service (CPU consumption from stuck connections) because connection_read_header_more in connections.c has a typo that disrupts use of multiple read operations on large headers. | |||||
| CVE-2018-19052 | 4 Debian, Lighttpd, Opensuse and 1 more | 5 Debian Linux, Lighttpd, Backports Sle and 2 more | 2022-03-31 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character. | |||||
| CVE-2022-22707 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2022-01-13 | 4.3 MEDIUM | 5.9 MEDIUM |
| In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system. | |||||
| CVE-2013-4560 | 3 Debian, Lighttpd, Opensuse | 3 Debian Linux, Lighttpd, Opensuse | 2021-03-04 | 5.0 MEDIUM | N/A |
| Use-after-free vulnerability in lighttpd before 1.4.33 allows remote attackers to cause a denial of service (segmentation fault and crash) via unspecified vectors that trigger FAMMonitorDirectory failures. | |||||
| CVE-2011-4362 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2021-03-04 | 5.0 MEDIUM | N/A |
| Integer signedness error in the base64_decode function in the HTTP authentication functionality (http_auth.c) in lighttpd 1.4 before 1.4.30 and 1.5 before SVN revision 2806 allows remote attackers to cause a denial of service (segmentation fault) via crafted base64 input that triggers an out-of-bounds read with a negative index. | |||||
| CVE-2014-2323 | 4 Debian, Lighttpd, Opensuse and 1 more | 5 Debian Linux, Lighttpd, Opensuse and 2 more | 2021-02-26 | 7.5 HIGH | 9.8 CRITICAL |
| SQL injection vulnerability in mod_mysql_vhost.c in lighttpd before 1.4.35 allows remote attackers to execute arbitrary SQL commands via the host name, related to request_check_hostname. | |||||
| CVE-2013-4559 | 3 Debian, Lighttpd, Opensuse | 3 Debian Linux, Lighttpd, Opensuse | 2021-02-26 | 7.6 HIGH | N/A |
| lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached. | |||||
| CVE-2013-4508 | 3 Debian, Lighttpd, Opensuse | 3 Debian Linux, Lighttpd, Opensuse | 2021-02-26 | 4.3 MEDIUM | 7.5 HIGH |
| lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network. | |||||
| CVE-2014-2324 | 5 Contec, Debian, Lighttpd and 2 more | 7 Sv-cpt-mc310, Sv-cpt-mc310 Firmware, Debian Linux and 4 more | 2021-02-24 | 5.0 MEDIUM | N/A |
| Multiple directory traversal vulnerabilities in (1) mod_evhost and (2) mod_simple_vhost in lighttpd before 1.4.35 allow remote attackers to read arbitrary files via a .. (dot dot) in the host name, related to request_check_hostname. | |||||
| CVE-2019-11072 | 1 Lighttpd | 1 Lighttpd | 2019-04-23 | 7.5 HIGH | 9.8 CRITICAL |
| ** DISPUTED ** lighttpd before 1.4.54 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a malicious HTTP GET request, as demonstrated by mishandling of /%2F? in burl_normalize_2F_to_slash_fix in burl.c. NOTE: The developer states "The feature which can be abused to cause the crash is a new feature in lighttpd 1.4.50, and is not enabled by default. It must be explicitly configured in the config file (e.g. lighttpd.conf). Certain input will trigger an abort() in lighttpd when that feature is enabled. lighttpd detects the underflow or realloc() will fail (in both 32-bit and 64-bit executables), also detected in lighttpd. Either triggers an explicit abort() by lighttpd. This is not exploitable beyond triggering the explicit abort() with subsequent application exit." | |||||
| CVE-2008-4360 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2018-11-29 | 7.5 HIGH | N/A |
| mod_userdir in lighttpd before 1.4.20, when a case-insensitive operating system or filesystem is used, performs case-sensitive comparisons on filename components in configuration options, which might allow remote attackers to bypass intended access restrictions, as demonstrated by a request for a .PHP file when there is a configuration rule for .php files. | |||||
| CVE-2008-4359 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2018-11-29 | 7.5 HIGH | N/A |
| lighttpd before 1.4.20 compares URIs to patterns in the (1) url.redirect and (2) url.rewrite configuration settings before performing URL decoding, which might allow remote attackers to bypass intended access restrictions, and obtain sensitive information or possibly modify data. | |||||
| CVE-2008-1531 | 2 Debian, Lighttpd | 2 Debian Linux, Lighttpd | 2018-10-31 | 4.3 MEDIUM | N/A |
| The connection_state_machine function (connections.c) in lighttpd 1.4.19 and earlier, and 1.5.x before 1.5.0, allows remote attackers to cause a denial of service (active SSL connection loss) by triggering an SSL error, such as disconnecting before a download has finished, which causes all active SSL connections to be lost. | |||||
| CVE-2006-0814 | 1 Lighttpd | 1 Lighttpd | 2018-10-18 | 5.0 MEDIUM | N/A |
| response.c in Lighttpd 1.4.10 and possibly previous versions, when run on Windows, allows remote attackers to read arbitrary source code via requests that contain trailing (1) "." (dot) and (2) space characters, which are ignored by Windows, as demonstrated by PHP files. | |||||
| CVE-2007-1869 | 1 Lighttpd | 1 Lighttpd | 2018-10-16 | 5.0 MEDIUM | N/A |
| lighttpd 1.4.12 and 1.4.13 allows remote attackers to cause a denial of service (cpu and resource consumption) by disconnecting while lighttpd is parsing CRLF sequences, which triggers an infinite loop and file descriptor consumption. | |||||
| CVE-2007-1870 | 1 Lighttpd | 1 Lighttpd | 2018-10-16 | 7.8 HIGH | N/A |
| lighttpd before 1.4.14 allows attackers to cause a denial of service (crash) via a request to a file whose mtime is 0, which results in a NULL pointer dereference. | |||||
| CVE-2008-0983 | 1 Lighttpd | 1 Lighttpd | 2018-10-15 | 5.0 MEDIUM | N/A |
| lighttpd 1.4.18, and possibly other versions before 1.5.0, does not properly calculate the size of a file descriptor array, which allows remote attackers to cause a denial of service (crash) via a large number of connections, which triggers an out-of-bounds access. | |||||
| CVE-2007-4727 | 1 Lighttpd | 1 Lighttpd | 2018-10-15 | 6.8 MEDIUM | N/A |
| Buffer overflow in the fcgi_env_add function in mod_proxy_backend_fastcgi.c in the mod_fastcgi extension in lighttpd before 1.4.18 allows remote attackers to overwrite arbitrary CGI variables and execute arbitrary code via an HTTP request with a long content length, as demonstrated by overwriting the SCRIPT_FILENAME variable, aka a "header overflow." | |||||
